METABOLIC CHANGES BEFORE AND AFTER PHYSICAL ACTIVITY

Abstract

Physical activity is an important factor in improving health and preventing disease due to the fact of being linked to control of both primary and secondary diseases. In this study, 21 players were used, who were submitted to a 36-minute-long training, with light runs of 5 minutes and 30 seconds of heavy run; subsequently, the time changed, with 1 minute of light run and 45 seconds of heavy run. The blood variables analyzed were lactate dehydrogenase, urea and absolute number of leukocytes. For this analysis, it was used the Statistical software, with a significance level of p d” 0.05. It was observed that there was a significant increase in lactate dehydrogenase of all athletes, due to the disruption of the membrane and leakage of this in the blood. The leukocytes also increased in all athletes since they stayed intercalated in the vessels’ wall, and in intense physical activity, they fall into the bloodstream. However, there were changes in the urea, but not significant in relation to Statistical Software, which was obtained significance > 5%; articles report that this increase may be due to increased protein catabolism as well as gluconeogenesis, by the effect of physical training practice. With these results, these metabolic changes during training happen because the body tries to meet energy expenditure during the practice of physical effort in order to try to adapt to the plight of energy and body fluids loss.
